HANGER FOR SUSPENDED CE ILINGS. I

Application filed March 30, 1925. Serial No. 19,322.

To all whom it may concern.

Be it known that I, J OIIN TASEFF, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful Improvements in 1 Hangers for Suspended Ceilings,'of which the following is a specification.

My invention relates to hangers for s'uspended ceilings for use in large buildings of modern concrete construction.

The primary object of my invention is to provide a hanger which may be fixed in the beams or concrete floorwork of buildings so as to extend downwardly therefrom and serve as supporting means for the usual ceiling framework to which the metal lath is attached.

Another object is to provide hangers of a form which will facilitate the o eration of suspending channel iron c'rossars which form the framework of the save time and labor.

Other objects and advantages will appear hereinafter and while I show herewith and will describe a preferred form'of construction I desire it to be understood that I do not limit myself to such preferred form but that various chan es and adaptations may be. made therein without departing from the spirit of my invention as hereinafter claimed. i

In the drawings which accompany this specification: I

Fig. 1 is a view, partly in'section, of one form of my improved hanger, fixed,.in the concrete floorworlq.

Fig. 2 is a view" similar to Fig. 1 showing a slightly modified formof hanger and illushating the positions of the channel iron bars held therein.

Fig. 3-is a view similar to Fig. 1 a hanger of slightly different form.

Fig. 4 is a view similar to Fig. 3 showing the sameform of supporting member with modified shank and anchor parts, also illustrating the positions ofthe channel irons in the hook member.

Fig. 5 is an enlarged view in perspective of the socket forming part of the shown in Fig. 1.

showing ceiling and thus of hanger shown in Fig. 1 consists of a hol- 1 bar 17.

ianger Fig. 6 is a view similar to Fig. 5 showing the socket which forms part of the hanger shown in Fig. 2.

Fig. 7 is a view similar to Figs. 5 and 6 showing the socket which forms part of the hanger shownin Fig. 3.

Figs. 8 and. 9 are views in perspective of similar hangeroparts which may be substie tuted for some of those shown in the other figures. a

Fig. 10 is a sideview of another form of anchor piece and suspending hook.

Fig. 11 is a side view of a single piece hanger of the samegeneral form as Fig. 4 but of dilferent construction.

ceiling, illustrating the appearance of a pair of channel irons in a hanger of the typeshown in Fig. 4 as see'n'from below and a method of attaching metal lath to the ohannel irons. i

:Referring to the parts in detail the form low metal socket 10 having a shank 11 and a cross bar-1'2 adapted to be imbedded in the floorwork. of a building so that the socket opening is flush with the under side thereof; a hook member 13 adapted to receive the channel irons and a supporting rod 14 adapted to connect the hook member and the socket member and to hold the former suspended in spaced relation to the latter. The socket member 10 isprovided with a slot 15 having a widened portion 16 shown in Fig. 5 to admit a bolt head for use in suspending water pipes and the like. A transverse bar 17 is fixedyinside the socket near one 'end of the slot. The hook member 13- is preferably a cast metal block short up-turned hook 18 on one side of its having a lower end and a relatively long 'up-turned I suspending rod 14-. which has its lower end screw-threaded to engage therewith and has a book 20 adapted to The hanger shown in Fig. 2 is similar to that shown in Fig. 1 except that the socket engage transverse 21 has a hooked lug 22 projecting from one of its inner sides instead of a slot and transverse bar, and is anchored in the concrete by a heavy wire 23 extending through ears 34 and bent upwardly and outwardly to form anchor pins 25. The hook member 13 has its upper end reduced to form alug 2b which has an aperture 27 to receive a hook 28 on the lower end of the suspending rod 29, the upper end of which has an eye 30 adapted to slip over hooked lug 22, there being sufficient space between this lug and the opposite side of the socket to admit said eye as shown in Fig. 6.

The modified hanger shown in Fig. 3 differs from those shown in Figs. 1 and 2 in that a different formof socket is used and the hook member is made so that it connects directly with the socket without a suspend ing rod. The socket is a block 31 of the form shown in Fig. 7 with a deep groove 32 in its under face and a vertical aperture in the center thereof through which an eye bolt 33 extends with the eye part 34 set transversely of the groove and the upper end 35 bent at a right angle to form an anchor 'pin.

The hook member 36 is made of a piece of.

angle iron which is split at its lower end and the flange parts bent upward to form hooks 37 and 38 corresponding .to hooks 18 and 19 respectively in Figs. 1 and 2. The upper end is reduced and bent to form a hook 39 adapted to engage with eye 34.

The hanger shown in Fig. 4 is similar to that shown in Fig. 3 execept that no socket is required in this'case, the shank 40 of the hook member being extended upwardly to form an anchor. This is done by splitting the upper end of the angle iron, collapsing the flanges along the part to be imbedded as at 41 and bending them apart at the upper end to form anchor lugs 42. A pin 43 extending through a hole in part 41 serves to hold the hanger in its properly adjusted position in the forms when the concrete is being poured.

Figs. 7 and 8 show similar anchor parts made of strap iron the upper ends of the pieces being split and the ends being bent in opposite directions to form anchor lugs 44. A loop 45 may be made at the form line 46 and a link 47 held therein may serve as an eye for engaging a hook 48 on a suspending strap 49, which may have hooks similar to those described formed on its lower end. Or the anchor piece may be extended below the form line as at 50 and holes 51 made therein in which bolts or rivets may be used lo connect the hook member or other parts.

' Fig. 10 shows an anchor piece 52 with a screw-threaded socket adapted to be set in the concrete flush with the form line, so that a suspending rod 54 with a threaded upper end; 55 may be screwed into it.

Fig. ll shows a single piece hanger simimadam lar to the one shown in Fig. 4 but made of thick wire or thin rod material. The piece is bent near its middle to form an anchor loop 56, has a right angled return bond 57 at the form line and the ends extend downalso parallel to each other. It being most convenient to place the upper series first it is evident that the bars 60 of this series must be lifted somewhat in order to allow the bars 61 of the lower series to be passed into the lower hooks. The upper hooks are made longer than the lower ones to provide for such lifting of the upper bars without their becoming disengaged therefrom.

As shown in Fig. 12' the metal lath 62 is applied directly to the channel irons and is attached thereto by pieces of wire looped around the irons at intervals so that their ends project downwardly through meshes of the lath and are twisted together to form a closed loop 63.

It is evident that some of the parts shown are interchangeable, that is, the socket parts and anchor parts may be used with other associated parts than those shown.

Having described my invention. I claim:

1. A hanger for suspended ceilings comprising a hook member adapted to be fixed in the floorwork of a building so as to extend therebelow, a short up-turned hook on the lower end of said hook member and a the longer rip-turned hook adjacent said short hook but above it and at an angle of 90 degrees thereto.

2. A hanger for suspended ceilings comprising a socket member and a hook memher. said socket member being adapted to be anchored in, the floorwork of a building so as to be flush with the under side thereof and said hook member being adapted to connect with said socket member so as to extend therebelow, a short lip-turned hook and a longer rip-turned hook formed on said hook member, said short hook being on the lower endthereof and said longer hook being adjacent said short hook but above it and at an angle of 90 degrees thereto.

3. A hanger For suspended ceilings com-- prising a socket member adapted to be. anchored in the fioorwork of a building so as to be'flush with the undersidethereof. a

hook member adapted to support the framea work of a ceiling and a. suspending rod formed on said hook member, said short 1 hook being on the lower end thereof and said longer hook being adjacent said short hook, but above it and at an angle of 90 degrees thereto.

4. In combination with the floorwork of a building a hanger for suspended ceilings comprising a socket imbedded in the floorwork so as to be flush with the under side thereof, and a hook member attached to said socket so as to be held in spaced relation 10 thereto; a short up-turned hook and a longer upturned hook formed on said hook member, said short hook being on the lower end of said hook member and said longer hook being adjacent said short hook but above it 15 and at an angle of 90 degrees thereto.
